Comments of chapter undefined of Chaos Devourer System

ok he should not add new genes, since he has 2 extra genomes already (Chaos Devourer and Astral Titan) and his initial Absolute Morph gene. But can he still use the Nuclear Radiation energy and the rare combat skill? Sure his path is Mana Cultivation, but he also uses internal energy for the Chaos Devourer skills. What would be the downside of having a 3rd source of energy, could it fuel the Astral Titan genome?
